Given numbers are 976,128,221,205

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 976,128,221,205 is 353741440.

Find LCM of 976,128,221,205 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 2 x 61 x 8 x 221 x 205 = 353741440

Therefore, the lowest common multiple of 976,128,221,205 is 353741440.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

976 x 128 x 221 x 205 = 5659863040

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976

128 : 1, 2, 4, 8, 16, 32, 64, 128

221 : 1, 13, 17, 221

205 : 1, 5, 41, 205

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 976,128,221,205, is 1.

Now, the common factors can be found like this.

976:2x 2x 2x 2x 61

128:2x 2x 2x 2x 2x 2x 2

221:13x 17

205:5x 41

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 2 = 16

Therefore, the value for common factors is 16.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 5659863040/(1x16)

LCM = 5659863040/16

LCM = 353741440

Thus, we can understand that the LCM of 976,128,221,205 is 353741440.
